RIVERTON, Wyo. (AP) — Authorities are investigating a bomb threat which canceled a meeting to discuss alleged problems at the Eastern Shoshone Housing Authority.

About 110 people gathered for Saturday’s General Council meeting at Rocky Mountain Hall in Fort Washakie were evacuated because of the threat. One attendee told the Associated Press  that the threat happened shortly after leaders declared there were enough people present to proceed with the meeting.

FBI spokesman Dave Joly confirmed the agency is among those investigating the threat.

Tribal members signed a petition calling for the meeting because of concerns with the housing authority. Housing authority officials say the petition was circulated because of bitterness over the firing of previous board members.

Five managers were terminated after a General Council meeting in February 2010.
